This is indeed a tricky problem. What I would suggest is looking at what 
is going on with the JSESSIONID cookie in the browser, and seeing if the 
cookie has the correct path. Normally with the emptySessionPath setting, 
the path should always be empty. If it is not it means that something is 
probably wrong with the Tomcat configuration.

This is a problem that is not specific to Jahia, but to any portal 
installation, such as Jetspeed 2, Pluto, etc. You might want to "google" 
a bit to see if you can find more details about this there.
